Trilogy Transformations!

With the score tied one apiece, bitter enemies Conor McGregor and Dustin Poirier will complete their trilogy in the UFC 264 pay-per-view (PPV) main event, a lightweight battle that ends a rivalry first started on the UFC 178 fight card way back in Sept. 2014.

That’s where McGregor drew first blood, courtesy of a first-round technical knockout. Poirier would later avenge that loss as one half of the UFC 257 headliner last January, leading to their July 10 rubber match inside T-Mobile Arena in Las Vegas, Nevada.

A lot has changed over the last seven years, including McGregor and Poirier.

First up is UFC 178 (145 pounds):
